here is the best way I have found for dealing with my black Z. First use the two bucket method to wash. then have a electric leaf blower to dry. dont use gas due to the fumes and such. But to really get that perfect look use a quality wash and wax system like Zanio or adams. I have used Zanio and love it. It takes a little more time but the car stays cleaner longer. as far as adams polishes I hear they are good to but have no personal experience with them. Zanio is available only online just google them. I use their claybar first, then the PC compound to get all the scratches and swirls out then follow up with their show car finish wax (z3 and z5 if I remember correctly) and finish with the spray detailer. I use this system 2 times a year and wash the car as before mentioned when needed and maintain with the spray detailer the rest of the year.
